摘　　要：对锂离子动力电池负极用材料:中间相碳微球(MCMB)、软碳(SC)进行了对比研究。发现MCMB在高倍率放电性能上表现较好,而软碳材料在高倍率充电性能方面更加突出。为得到在高倍率充电、放电性能两方面都比较优越的负极材料,对MCMB和软碳进行了不同比例混掺的研究,结果表明:当MCMB与软碳的混掺比例达到5∶5时,电池的大倍率充放电性能表现较优越,能够满足功率型电池应用的需要。Mesocarbon microbeads（MCMB） and soft carbon（SC） commercially used anode materials of lithium ion power battery were compared.It is found that the rated discharge property of MCMB is better than SC,while the rated charge performance is more excellent than the other.In order to achieve satisfactory rated performances of both charge and discharge,the mixing proportion of MCMB and SC was researched.The results show that when the ratio of MCMB and SC reaches 5∶5,the superior rated charge and discharge properties are obtained,which can meet the performance need of the high-power lithium ion battery in application.
